Both the VST plugin and the standalone version of Monique are lagging pretty bad on my Mac. I'm running OS X 10.11.6 on a MacBook Pro, 2.8Ghz i7, 16GB RAM, Radeon R9 M370X. As long as Monique doesn't play any notes the interface is responsive, but when it starts playing all the knobs, OSCI visuals etc. start to lag and stutter. This makes the synth barely usable :C

PS: I didn't try the AU plugin as my DAW doesn't support it, I only tried VST and standalone app.
